- Global spatially explicit yield gap time trends reveal regions at risk of future crop yield stagnation. For 8 of 10 major crops, yield gaps have widened steadily from 1975 to 2010 over most areas, and remained static for sugar cane and oil palm. Time to turbo-charge the breeding?
- Domestication and the evolution of crops: variable syndromes, complex genetic architectures, and ecological entanglements. If you want to turbo-charge breeding, you need to understand (among other things) the ecological context of domestication.
- Including Traditional Ecological Knowledge (TEK) in Agricultural Research: Guidelines and Lessons Learned. I suspect Traditional Ecological Knowledge can help with figuring out the ecological context of domestication.
- High levels of genetic variation and differentiation in wild tropical gourds provide a novel resource for cucurbit crop improvement. Ok, but ecological knowledge would like a word.
- Understanding genetic diversity in drought-adaptive hybrid parental lines in pearl millet. Any link to ecology of original collecting sites, I wonder?
- Genetic Diversity and Population Structure Analysis of a Diverse Panel of Pea (Pisum sativum). Again, ecological knowledge conspicuous by its absence. Maybe the passport data just weren’t up to it?
- Banana seed exchange networks in Burundi – Linking formal and informal systems. Yes, yes, it’s not just about the breeding, the seed system also has to work.
- Editorial: Current status of honey bee genetic and breeding programs: progress and perspectives. Pollinators need breeding programmes too.

- Food matters: Dietary shifts increase the feasibility of 1.5°C pathways in line with the Paris Agreement. Go flexitarian.
- Biodiversity footprints of 151 popular dishes from around the world. Go flexitarian?
- Periodic Table of Food Initiative for generating biomolecular knowledge of edible biodiversity. Unclear if flexitarians have the best molecules.
- Environmentally protective diets may come with trade-offs for micronutrient adequacy. More sustainable may mean less nutritious. Flexitarians unavailable for comment.
- Market engagement, crop diversity, dietary diversity, and food security: evidence from small-scale agricultural households in Uganda. Market access and crop diversification are both good for dietary diversity and food security. The ultimate flexitarianism.
- Sustainability of one-time seed distributions: a long-term follow-up of vegetable seed kits in Tanzania. Now watch flexitarians demand an even playing field.
- Developing holistic assessments of food and agricultural systems: A meta‑framework for metrics users. One framework to rule all of the above.
Giving a fig
Jeremy’s latest newsletter is out, with a medium-deep dive on a deep dive on figs. There’s more on FIGGEN here. And FYI, Genesys shows about 1500 fig accessions in genebanks.
AramcoWorld is a glossy publication from the Saudi oil giant that covers all sorts of topics generally linked to the Muslim world. In the latest issue a deep dive into fig diversity. For the scientifically inclined, FIGGEN is a cooperative effort to collect figs wild and cultivated and decode links between DNA and desirable qualities. The heart of the story, however, is the Tunisian farmers working to keep ahead of the climate emergency by changing the varieties they grow and the ways they grow them.
Read it, and you too will be able to speak knowledgeably about caprification, and if you can find an etymology beyond something like goat figs, do let me know.

- Frugivory by carnivores: Black-backed jackals are key dispersers of seeds of the scented !nara melon in the Namib Desert. Jackals pee on wild melon relatives and disperse their seeds, not necessarily in that order.
- Out of the Shadows: Reestablishing the Eastern Fertile Crescent as a Center of Agricultural Origins: Part 1. Go East, young archaeobotanists!
- Extinction risk predictions for the world’s flowering plants to support their conservation. Fancy maths says 45% of angiosperms are potentially threatened. Same for crop wild relatives in the Eastern Fertile Crescent? Black-backed jackals unavailable for comment.
- Global Wild Rice Germplasm Resources Conservation Alliance: WORLD WILD-RICE WIRING. Scientists get together to conserve global wild rice germplasm resources, understand the ecology of wild rice environments, identify and address threats, define effective ways to use wild species in rice improvement, and provide data for decision-making. Not a minute too soon, given the above.
- Morphometric analysis of wild potato leaves. Who needs genotyping anyway.
- Large-scale gene expression alterations introduced by structural variation drive morphotype diversification in Brassica oleracea. Brassica scientists need genotyping, apparently, that’s who.
- Exploring the nutritional potentials of wild Vigna legume species for neo-domestication prospects. Not much potential if they go extinct though. Quick, photograph their leaves!
Brainfood: Archaeology edition
- Early human selection of crops’ wild progenitors explains the acquisitive physiology of modern cultivars. The high leaf nitrogen, photosynthesis, conductance and transpiration of crops was already there in their wild relatives, the first farmers just happened to domesticate greedy plants.
- The impact of farming on prehistoric culinary practices throughout Northern Europe. When the first farmers arrived in northern Europe armed with their greedy plants, they learned a lot about food from the local hunter-fisher-gatherers, and vice-versa, but without much interbreeding. Jeremy interviews one of the authors on his podcast.
- Early contact between late farming and pastoralist societies in southeastern Europe. There was extensive interbreeding between farmers and the local transitional foragers/herders before with the expansion of pastoralist groups into Europe from the Eurasian steppes around 3300 BC.
- Isotopes prove advanced, integral crop production, and stockbreeding strategies nourished Trypillia mega-populations. The earliest European mega-settlements, in Ukraine and Moldova, from around 4000 BCE, integrated greedy crops and generous domesticated livestock.
- Inference of Admixture Origins in Indigenous African Cattle. Following introduction from the Near East, domesticated cattle got admixed with a North African extinct aurochs before spreading throughout Africa.
- Flax for seed or fibre use? Flax capsules from ancient Egyptian sites (3rd millennium BC to second century AD) compared with modern flax genebank accessions. Fibre first.
- Revealing the secrets of a 2900-year-old clay brick, discovering a time capsule of ancient DNA. DNA from 34 plant groups were detected inside an old brick when it happened to break.
- Making wine in earthenware vessels: a comparative approach to Roman vinification. Comparison with modern counterparts shows that Roman clay jars for storing wine were integral to the process. No word on whether there was any ancient DNA in the clay.
- Breadfruit in the Pacific Islands, its domestication and origins of cultivars grown in East Polynesia and Micronesia. Spoiler alert: they came from Polynesian Outlier Islands.
